Flat-spired three-toothed snail[Triodopsis platysayoides]
The flat -spired three-toothed snail is approximately 1.2 inches in diameter and up to .4 inches thick. It has a thin, flattened, five-whorled shell, that is light brown to light reddish brown and with oblique banding. A thick, white cone shaped tooth is present on the shell's inner wall. It feeds primarily on lichens on rock surfaces and in leaf litter in deciduous and mixed-pine forests and is occasionally known to feed on other snails. Scientists estimate that densities of less than 4 snails per square foot are necessary to prevent cannibalism. Cool, damp, shaded areas are ideal habitats for this snail but during hot, dry weather it is known to retreat into crevices of sandstone boulders.
This species is extremely rare and is endemic to West Virginia. It inhabits an area below the summit of Cooper's Rock adjacent to Cheat River Canyon that is partly contained in Cooper's Rock Recreation Area, part of Cooper's Rock State Park. Population estimates in the 1970's suggested 300-500 individuals but more recent studies estimate that the population could be approximately 1,000 individuals.
Very little is known about this species regarding reproduction, distribution, and habitat requirements. However, heavy recreational traffic around Cooper's Rock disturbes the leaf litter in which the snail forages. State park personnel have fenced and rerouted hiking trail to eliminate disturbance and are investigating further conservation plans.
